Page 3: Introduction
1 INTRODUCTION The tapping machine HD 2040 is a normalized impact noise generator for the measurement of sound insulation of floors according to ISO 140-6, ISO 140-7, ISO 140-8, ASTM E492 and E1007. It has 5 hammers in line driven by a motor controlled by an electronic system, by means of camshaft.

Page 5 Bubble level for horizontal levelling. Level gauge placed on the rear panel of reference for checking the height of fall of the hammer. The level gauge enters its site with a little pressure; pull to remove. Support feet with height-adjustable rubber base. The legs can be rotated under the base to reduce the footprint of the machine.
Page 6: General Information About The Measure
3 GENERAL INFORMATION ABOUT THE MEASURE The sound insulation of floors is measured by operating the machine on the test floor and measuring the level of noise in the underlying. The method of measurement is defined by ISO 140-6, ISO 140-7, ISO 140-8, ASTM E492 and ASTM E1007.
Page 7 The isolation of a structure is assessed by the level of impact noise normalized with respect to the sound absorption: × [dB] or by the level of impact noise normalized with respect to the reverberation time: × [dB] where: = average level of sound pressure measured at several points of the receiving environ- ment when on the surface under test the impact noise generator is in action.
Page 8: Installing The Battery
4 INSTALLING THE BATTERY For security reasons, the machine is delivered without the rechargeable lithium-ion battery in- stalled. Before you start using the unit you have to install the battery supplied. Install as shown below: 1. Make sure the power switch is OFF and the power cable is disconnected. 2.
Page 9 4. Insert the battery into the holder, making sure that the cable connecting the battery comes out towards the front panel of the machine. HOLDER ATTERY ONNECTOR 5. Attach the battery holder to the unit structure. 6. Connect the battery to the circuit board, observing the correct polarity. The connector has a polarizing key that prevents the possibility to insert the plug incorrectly.

5 PREPARATION OF THE MACHINE ATTENTION: HE UNIT HAS MOVING MECHANICAL PARTS SO MAKE SURE THAT THE POWER SWITCH IS SET TO AND THAT THE POWER CABLE IS UNPLUGGED BEFORE PERFORMING THE OPERATIONS DESCRIBED IN THIS CHAPTER The tapping machine is supplied with the feet retracted in the transport position. To prepare the machine for normal operation it is necessary to rotate the three feet in the working posi- tion.
Page 11 If adjustments are needed, proceed as follows: 1. Unlock the feet by using the supplied 13 mm wrench. 2. Place the gauge along the line of the hammers, as close as possible to the foot to be checked. 3. Screw or unscrew the feet to adjust the height, checking with the spirit level that the ma- chine is on an horizontal plane.

6 OPERATION OF THE MACHINE OWER SUPPLY The machine operates with 100…240 Vac by mains or powered by lithium-ion battery 7.2 V / 2900 mAh housed inside the machine. CAUTION: The machine is shipped without the battery installed. Before starting the machine, install the battery following the instructions in Chapter 4.
Page 13: Starting And Stopping The Motor
TARTING AND STOPPING THE MOTOR WARNING: HE MACHINE HAS MOVING MECHANICAL PARTS MAKE SURE NOT TO CAUSE DAMAGES TO PEOPLE OR THINGS DURING THE OPERATION OF THE MOTOR O NOT MOVE THE MACHINE WHEN THE HAMMERS ARE WORKING After turning on the machine, in order to start the movement of the hammers press the START button on the front panel or the remote control button.
Page 14: Enable And Disable The Remote Control
7 ENABLE AND DISABLE THE REMOTE CONTROL The remote controls have an identification code that is transmitted to the machine when you send a command. Only if the code is recognized by the machine, the command to start or stop the motor is executed.
Page 15: Maintenance
8 MAINTENANCE WARNING: AKE SURE THAT THE POWER SWITCH IS SET TO OFF AND THE POWER CABLE IS UNPLUGGED BEFORE ANY MAINTENANCE OF THE MACHINE If the LED indicators of the proper functioning of the hammers signal anomalies in the fall speed or impact interval, clean and lubricate the hammers.
